T 0 all whom it may concern xle it known. that .l, (tron i i. t-lwion, oi? San Francisco, in the county of tian Francisco. and in the State of t alitornia. have invented a certain new and useful improvement in laper-lntertolding ll'lachines. and do hereby declare that the following is a full, clear, and exactdescription thereof.

My invention relates particularly to a machine designed to produce tolded sheets of paper, as for example for use as towels, etc, either craped or plain.

The object of my invention is to provide a machine of this kind which is adapted to produce packs of folded paper sheets, said packs being so arranged that when one of the lower slieets of the pack is pulled downwardly, it is readily removed from the pack and, at the same time, withdraws the free end of the next succeedimo; sheet of paper so that said next succeeding sheet may he readilv Withdrawn in a similar manner from the lower end of the pack. Such packs of folded sheets are customarily retained in a box having; an open slot at its bottom so arranged that the free edge of the lmveru'mst sheet projects through the slot so to per-- wit the removal of the sheets, one after another, in the manner above described. The box or means used tor retaining the pack of folded sheets for use, however. forms no part of my invention herein. it "further object of my invention is to provide a machine of the above character which is adapted to produce packs of folded paper sheets from paper rolls. .rri'iother object oi? my invention is to provide a machine of the above cluuacter, which is soarranged as to op-- crate continuously. Further objects of my invention will appear from the detailed description thereof appearing hereinafter.

While my invention is capable of e1nhodiineut in many different forms for the purpose of illustration I have shown only one form thereof in the accompanying drawings in which,

in the drawings 1 have shown a paper interiolding machine having;- two lower side frames 1, adapted to be c nnected to; .thcr and retained in place by connecting rods 2. Upon the tops of the lower side *lrames 1, ther are supported two upper side 'lframes The upper side ttralnes 15 are arranged to receiver. main driving shaft having a tight pulley t), and a loose pulley 'i' thereon. adapted to be connected with any suit.- able source of power, ilpon the extreme end of this shall; there is located a hands wheel 8. which may erve. when desired. as a wheel for imparting a degree of movement to the mai h i in threading the paper into the machine at the start. Thi main haft 3 constitutes the shaft for supporting a female cutting cylinder 9., whichcooperates with a male cutting); eylindcr 10, located adjacent thereof. On the sha it oi the female cutting cylinder 5.) there is, furthermore a gear it. which meshes with a gear 12 located on a shalt 1 supporting the male cutting cylinder it In mes-d1 with the gear 11 there is also a gear ill on it shaft 15 which carries a paper ceding: cifvlinder 16, against which there rests a t nsion roll 17. located on arms r-aupporteiil upon a shaft 19 around which there are lotlated springs 20 for pressihgz the tension rolls 17 against the surface tlil't tl el'feeding roll 16. The tension roll 17 i adailited to receive :1 paper web A. which malx dbe either eraped or plain. The gear l'l. ttrtllei-more. 'ileshes with a further afar ill. on a shaft 22. which carries an tinted, dihg cylinder 23\ "which gear 2i in tulfih meshes with a. gear '24 on a shaft 25 carrying a rotary tumbler cylinder gear 26. The same gear 21 also meshes with a gear 27 on a shaft 28, which shaft has a smaller gear 29, meshing with a gear 30 on a shaft 81, carrying a roll to receive a pair of conveying tapes 33 passing therefrom to a roll 34:, which also receives a further pair of conveying tapes 35. The parts thus far described are located on one side of the machine, the parts on the other side of the machine being constructed in the same manner, except that the last mentioned parts are driven from the main driving shaft 5 already described, and contain, in addition, some further parts to be described hereinafter. These parts are driven in the following manner: The gear 21 meshes with a gear 36 on a shaft 37 carrying another paper inter-folding roll 38. This gear 36 meshes in turn with a gear 39,011 a shaft 10, carrying a further rotary tumbler cylinder gear ll. The gear 36, furthermore, meshes with a gear 42 on a shaft #13 carrye ing another female cutting roll 44, said gear 4-2 in turn meshing with a gear 15 on a shaft 16 carrying a male cutting roll 47. Furthermore, the same gear 42 meshes with a gear 18 on a shaft 49, carrying a feeding roll 50, and said gear 18 meshes with a gear 51 on a shaft 52, carrying a printing bed cylinder 53. The gear 51 in turn meshes with a gear 54- on a shaft 55, carrying a printing roll 56, to mark the web of paper at measured intervals, so as to provide paper packs of equal size, which coiiperates with an inking roll 57 on a shaft 58 carried in an arm 59 supported upon a rod 60, passing through the upper side frames 3. In contact with the feeding roll 50 there is also a tension roll 61 supported upon arms 62 carried by a shaft 63, having springs 6 1- to press the roll 61 against the surface of the feeding cylinder 50. A paper web B is fed into this side of the machine over the shaft 63, and then between the rolls and 56. From the above, it will be seen, that the machine is provided on the two sides of the machine with duplicate tension rolls 17 and 61, feeding rolls 16 and 50, male cutting cylinders 10 and 47, female cutting cylinders 9 and 44, paper interfolding rolls 23 and 38, and rotary tumbler cylinder gears 26 and 41.

The paper web A, being fed into the machine between the ten in rolls 17 and the feeding rolls 16, passe around the feeding rolls 16 and thence around the female cutting roll 9. The female cutting roll 9 is provided on opposite sides with longitudinal troughs 65, in which there is supported a pair of bars 66 and 67 sp ced apart by sleeves 68 through which pass screw-threaded holes 69 .for recei ing Eljusting boltd 70, having nuts 71 on their e dsi, The bars 66 and 67 are held in b means of a screws 72, which pass rough' slots 73 intheir'ends and'into tlae body 0, the cutting cylinder 9, the adjustment of the bars 66 and 67 being obtained by first loosening the screws 72 and then adjusting the bolts 70, the heads of which rest against the side of the trough 65. The bars 66 and 67 are so arranged as to leave a cutting slot 74: between the same. These slots 7+1 are designed to register with knives 75 carried on brackets or bars 76, located on opposite sides of the male cutting cylinder 10. The brackets or bars 76 are provided with screwthreaded openings 77, to receive adjusting screws 78 adapted to fit within recesses 79 on the opposite sides of the cylinder 10, on which the bars 76 are located. Furthermore, these bars or brackets 76 are arranged near their ends with slots 80 to receive screws 81, which retain the bars 76 in their adjusted positions. These bars 76 are, furthermore, provided adjacent to the knives 75 with strippers 81, having extensions 82 resting upon the top of springs 83, located on said bars 76 and the strippers 81 are arranged so that their movement is limited by screws 84 screw-threaded into openings in the sides of the bars 76. On the opposite sides of the knives 75 to the strippers 81, there are loccive one of the folding blades 88 of which there are two located on opposite sides of the cylinder 23. Each. of these folding blades 88 is supported upon a bracket 89 located in a trough 90 (Fig. 2) in the face' of the cylinder 23, and is adapted to be adj usted by screws 91 which pass into screw threaded holes on opposite sides of the bracket 89. Screws 93 passing through slots 91 in the ends of the bracket 89 hold the bracket in its adjusted position. The bracket 89v is provided at intervals with slots 95 which correspond in position to the connecting holes produced by the notches 87. It will be noted that the blade 88 is broken at intervals and extends between the several slots 95 and between the two end slots 94, and the ends of the bracket 89, said blade 88 being held in position by a plate 96, said plate 96, blade 88 and the bracket 89 being provided with holes 97 to receive screws 98 screw-threaded into the bracket 1 ,aosaeeo slots 102 in the cylinder 23, and below the troughs 90, and they are adapted to be re tained normally at the bot-tom of said re cesses 102 by springs 103 located in recesses 101 in the bars 100. These tongues 90 are adapted to be moved by lever arms 105 car ried upon shaft: 106 nd adapted to rest beneath the bars 100. Secured on the shafts 100 there are located, furthermore, lever arms 107 (Figs. 2 and 3) having rollers 108, which bear upon the outside of a cam 105,) located on the shaft 22. The contour of the cam 109 is such that the knife-edged tongues 09 are flush with the surface 01 the cylinder at the position of the cylinder 23 where the tongues 90 come adjacent to the cylinder 9, but thereafter, the tongues 09 are moved outwardly gradually by an inclined portion 110 (Fig. 2) onthe cam 109 until they are flush with the outer edge of the blade 88. Thereafter, the cam 10%) is provided with a sharp rise 111, so, as to extend the tongues 99 above the surface of the blade 88, to severthe connecting portions in the g paper web produced by the notches 8?, and

to complete y sever the paper sheet from the body of the paper web being fed into the machine. As previously stated, the two paper intertohling cylinders 23 and 38 are constructed exactly alike, but they are positioned in such a manner that the folding blades 99 on one cylinder register with the gripping means on the other cylinder, the gripping means being positioned 90 away from the blades 88 on each of the paper interfolding cylinder-d. The gripping means is comprised of stationary gripping jaws 113 held in place on the cylinder by screws 111- and springr-p1essed rotary gripping jaw 115, which are located on a shaft 110 to which there is attached an arm 117 (Fig. 2) having a roller 118, which is arranged to run within a' cam 11$),carried by the shaft 22.

The other web of paper B is fed into the machine and reaches the corresponding paper interfolding cylinder 38 in the same manner and through the same series of operations as in the case of the paper web 11 except in the 'l'ollowing respects: The paper web B is fed into the machine between the printing; bed cylinder 53 and the printing cylinder 50. the purpose of said cylinders being, to print a mark upon the paper web B in such a way as to provide 150 intertolded paper sheets in each package when the packages are severed opposite the marks provided by'the two cylinders referred to,

"the mark being so located that it overlies one of the folded edges in the packs of folded sheets so as to be readily seen by the operator, and so as to permit severance of the packs at that point by the operator, as the folded sheets pass out of the machine. Theprinting of the marks upon the web of paper the intervals above referred to,

accomplished in the following manner. The gear 51 on the shaft is provided with sc enty-tour teeth, while the gear 51 on the shaft is provided with seventy-five teeth, so that the teeth on 5-1 will gain one tooth at every revolution thereof, and, in other words, a given point on the gear 51 will come opposite to the same point on the gear 51 at each seventy-five revolutions of the gear 51, the marks being designed to measure oil a distance to provide each pack with seventydive double sheets, that is to say, 150 single sheets. The gear 51 is provided with a stationary plunger 120, to which itis held by a screw 121 and a pin 122. The gear 54', on the other hand, is provided with a movable plunger 123, having a tooth 121, projecting upwardly opposite one of the recesses between two adjacent teeth in this gear, and this movable plunger 123 has, furthermore, a longitudinal slot 125, which communicates with one end of a lever 120 located on a clamp 127 secured to the shaft 55 in such a manner that. the other end of the lever 120 communicates with a printing marker 128 in a slot 129 in the roller 50, which marker 128 is adapted to be normally retra'ted by a spring 130, and arranged to be rcmovably held in place by a plate 131 secured to the roll 50 by screws 132. In the rotation of the printing cylinder 50, ink is supplied to the marker 128 from the inking cylinder 57, which is a composition'roll of the usual kind provided for inking type. From this point the web of paper passes over the top of the feeding cylinder 50, then between the female and male cutting cylin' dcrs -14 and 47, and then finally on to the paper interi'olding cylinder 38. The two webs of paper A and -I) located on the interlolding cylinders 23 and 38 respectively, are now intert'olded by said cylinders owing to the fact that the blades 88 and the knifecdged tongues 0!) project the webs of paper into the gripping jaws 113 and 115, which are maintained open by the cam which operates the same at the point where the blade 88 and the knitwedged tongues 0!) come opposite said gripping jaws. lnnnediately after this. the gripping jaws 11:3 and 115 are brought together to 'lold one web between two partially scvcrcd portions and the other web at a partially sevcrcd portion, by the action (it the springs actuating the jaws and owing to the release of the roller 118 by the cam 11!) cooperating with the same, and innncdiately thereafter, the knife-edged tongues 00 make a sharp movement toward the gripping jaws 113 and 115 by the sudden rise 111 in the cam 10!), thereby severing the connecting portions of one web left by the notches 87, and thus entirely severing;- one sheet of paper from the web of paper to which it. was attached and intcrtolding the other web therewith. Further rotation of the interfolding rolls 23 and 38 thereafter removes the blade 88 and the tongues 99 from the gripping jaws 113 and 115. The folded web of paper carrying the severed sheet in the fold is now carried around by one of the intert'olding cylinders, as for example, the cylinder 23 until it reaches a point on the underside of the cylinder, directly below the center of the cylinder, but a short distance before the center of the cylinder is reached, at which point the rotary gripping jaw .1157, holding the same, is released through the action of the cam 119. At'the sametime, stripping arms 132. which normally run in grooves 133 on the cylinder and which are pivotally supported upon a shaft 134 operated by an arm 135, having a roller 136, which runs on a cam 137 (Fig. 3) on the shaft 2:2, are moved outwardly by springs 138 on the shaft, 13 thus removing the folded paper from between the jaws 113 and 115, and pressing the same down upon a stationary tumbler 139, The fold of paper which is now supported between the strippers 132 and the tumbler 139 is removed from between the same by a revolving tumbler bar 1+0 located on a shaft 141, which has a gear 1-12 in mesh with the gear 26, so as to rotate the same at the proper speed to remove the folds from between the stripber blades 132 and the stationary tumbler 139 at the proper intervals. The same action takes place in the same way at the other side of the machine where parts constructed exactly the same are provided for operating stripper blades 132* in connection with a stationary tumbler 139, and cooperating with a rotary tumbler 140 located on a shaft 1&6 having a gear 147 meshing with gear 41 on a shaft 40, which shaft 1-0 has a fur ther gear 39, meshing with the gear 36. The folded webs of paper are thus 'fed downwardly in zigzag shape to the upper surface of the conveying tapes 33 so that said webs are thus'continuouslyfed out of the machine, and on to the conveying tapes 35, at which point the packs of folded sheets containing 150 single sheets'or 75 double sheets may be severed by the operator at the points indicated thereon by the marks which have been applied by the printing devices on the machine. These packs of paper, as suggested above, are now ready for use, as for example, by insertion in a box containing a slot at its lower surface in sucha manner that the free edge of the lowermost sheet of paper projects out through the slot. When a sheet of paper is to be used, it is merely necessary to pull the free projecting edge of the lowermost sheet of paper, which withdraws said sheet from the pack, while, at the same time,

pulling out from the slot the free edge of the next sheet of paper contained. in the pack. The sheets of paper in the pack may then be successivelv removed'from the pack,

until the entire pack of paper sheets has been used. As stated above, these of paper sheets may be of plain or paper, and" they may be used for any de sired purpose, but they are especiaily as ist as paper towels.

While I have described my inve' above in detail, 1 wish it to be under that many changes may be in?" without departing from the spirit of n vention.

I claim: 7
